Application filed September 80, 1911. Serial No. 652,161.

To (1Z2 whom may, concern Be it known that we, John: Li'in 1o Kiiimvis'r and G'L'STAF Lixniix, subjects of the King of Sweden, residing. respeclively, at Aclelsii, Ekerii'. near Stockholm. in lhe Kingdom of Sweden, one at Niissjo. in the District of Joukoping, in the Kingdom of Sweden, have invented ne and useful improvements in ii nitting-Machincs, of which the following is a specification, reference being had to the drawings zmcoinpanying ancl forming a par-l hereof.

It is Well known that knittingmachines are adapted to he used for making several articles especially mulerwear and other articles of clothing which are of great importance for home and. for daily use. A knitting-niacinire is, therefore. an implement which should he equally general in use as for insiauce the sewing machine. This is, however, not the case. lhe reason for this seems lo be that the luii'rtinganachines are too complicated in construction and on account thereof too expensive, so that the, public in general cannot procure them. It is true that a liiii'lLlli.-il1iiL'l|lIiQ of the Well known 'l pe is rery perfect in respect to capacity of producing, articles of clolzhing of all kinds, but for lmitiing hose and stockings or othcr simple articles generally used ii is unnecessarily complicated and, on account thereof, unnecessarily expensive.

The object of the iuvenlioi'i is to provide a, knitting-machine especially adapted for knitting hose and si rilar things and which is extremely simple in construction so as to represent a price making it possible for most people to procure the same.

The invention C(l "isisls, chiefly. this that the needles are placed with their hooks outward in radial or suhslautially rarlial (lirec lliOIlS in a suitable horizontal circular bed along the periphery of which the yarncsuirle is movable in one or both directions.

The invention further comprises lhe cousir-action and con'iiiimuiou of parts hereinafter set forth.

In the drawings, We h shown a knitting-machine enilioriying the invention.

Figure 1 is a vertical section of the machine. Fig. 2 is a top plan view or the some. Fig. 3 is a bottom plan view of the upper plato delacherl?" Fig. i is a lop plan view of the needle hcrl. Fig. 5 is a bottom plan view of a modified form of the upper plate. Fig. i is a Vertical section of a modified form of the machine.

Referring to the drawings, the needle bed consists of a lower stationary dial or disk 1 suitably circular in shape and provided at its upper side, near its circumference, with grooves for the needles, as shown in Fig. i. Placed on the said disk 1 is an upper circular disk 2 aclaplecl to turn in either diriection about a pivot pin 3 (Fig. 1) projecting from the (lisk 1. The (llfk 2 carries the yarn-guide with the. yarn-engaging spring devices 9 and 10 and the operating members or cams for the needles. The lower disk 1 is carried by a Sifllllllll'kl suitably formed uy two tubes i and 5 one placed within the mixer no thal; the standard may he cx'reurlezl or reduced in length according lo the lcuglh of the Work. "The inner tube 4 may lie clamped in the outer one 5 by means of a screw 6 screwed into a. sleeve 7 and acting to compress the outer tube 5 against the inner one. The yarn passes from a reel 8 placcrl in the foot of the standliI'll, as shown in Fig. 1, through the hollow standard and the hollow pivot pin 3, thence through a spring hook 9 attached to or formed by an arm 51 attached to the opcratilz'igr arm or crank 12. farllfcr through an eye at. the outer end of a spring arm 10 likewise attached to the operating arm 12, thence through an opening 11 in the arm 12 and finally through the yarn-guide 13 placed at the outer curl of the arm 12 through which ill passes from above clownwarrl. The crank arm 12 is adapted. to turn a certain distance relatively to the disk 2. said distance being limited by stops [is at the upper sirle of the said (lisk.

Placed at the lower side of the (lisk 2 are the operating members for ihe needles 15. These park consist, chicliy, ol two fixerl operating cams 1T projecting: from the lower sirle of the \llSli 2 auil a triangular operating cam 1o movable in a radial (li rcction helween the fixerl cams and having its inner straight edges parallel to llw adjacent edges of the fixed cams so that the cams will form between them an angular groove of a variable width (scc li zr. 3). The hurts 18 of the needles 1:3 proiect above the needle herl formed by the rsh l, as

clearly shown in 1. When the needle butts are in the path (zb indicated by dashed and dotted lines in Fig. 3, the needles are in operative or working positions, the outer edges or the cams 1T lying, just in line with the said path. The outer parts of the triangular cam 16 cross the said path so that one or the other side of the said cam strikes the needle butts and moves the needles inward in the angular groove be tween the cams. The size of the loops formed 2 e. fineness of the knitted fabric is dependent on the position of cam 16 relatively to the cams 17 the loops being a longer as the cam 16 is moved toward the cams 17.

Projecting from the cam 16 into a radial slot 20 (Fig. 3) in the disk 2 is a suitable square sliding member 19 guided in the slot during the adjustment of the cam. The sliding member 19 is pivotally connected to a link 2-1 the other end of which is connected to a lever 23 adapted to swing about a pivot pin 22, the free end of said lever forming a and or pointer movable along a scale 24. The loop size may thus be easily adjusted. if it be desired to bring all the needles out of operative position this may be easily efiected by moving the cam 16 close onto the cams 17. In this position of the cam 16 the arc-shaped outer edge of the cam forms a continuation of the outer edges of the cams 17 as indicated by dashed and dotted line 27 in Fig. 3. The cam 16 is thus entirely inside the circle formed by the needle heads so that the needles will not be actuated.

When the needles are moved outward, they liable to move by inertia beyond the outer edge of the cam 16 in case no means are provided forretaining them in operative positions. To this end guard cams or abutmerits for the needle butts are provided outside the ends of the angular groove. It is easily seen that these ahutinents do not prevent the needle butts frmn entering the said groove. As shown in 3, the lower side of the disk 2 leaves free space for the needles which extends from the circumference of the dilr up to an extension 26 at the center of the same, exceptrat the place occupied by the cams and at the diametrically opposite part of the disk. The needles may therefore be freely moved by hand inward or outward. This considerably simplifies the change of needles to be operated. Thus if certain needies are to be brought out of action they may be simply pulled outward by hand into positions in which their butts lie in the path indicated by the dashed and dotted line h-d Fig. 3. In this position of the needles the nee le butts bear en a flange 28. rejecting downwardly at the edge of the disk 2,. in which position the needles are outside the path of the 16 so as to remain inactive.

When the'needles are to be thrown into operation they need only be moved 121- Ward by hand into positions in which they are reached by the cams.

H the needles are pushed inward by handinto positions in which their outer ends are entirely inside the circumference of the disks, the needle heads will be moved by the inner sides of the cams 17 into the path in dicated by the dashed and dottedfline e--f (Fig. 3), by which the needles are placed in inoperative positions In order to again place the needles in operative positions two guiding tongues 29 are provided one or the other of which maybe thrown into action according as the disk is rotated in one "or the other direction. -When the needles are in inoperative positions, the tongues 29 are placed close up to the central extension 30. of the disk. It the needles are to be projected into working position, one of the.

tongues 29 is swung outward into the position shown by dashed and dotted lines in Fig 3. In this position the tongue acts on the inner ends of the needles so as to move the needlc'hutts into positions in which they are caught by the outer side of a crescent like part 31 projecting from the disk 2 and moved back into the path 0ft). The swinging of the guiding tongues 29 is effected by handles 32 placed at the upper side of the disk 2 and adapted to be locked in positions by auy'suital'ile means (not shown).

When the needles are in their inward inoperative positions, the needle butts are inside the inner ends ofthe grooves in the needle bed. in moving the needles outward they must therefore be actuated in such a manner that they will not be brought into oblique positions in which the butts extend at an angle to the grooves so that the needles cannot be introduced into the same. This is secured by causing the tongues 29 to act directly on the ends of the needles so as to press on the needles in line with their shanks so as not to induce any turning movement of the shanks in the grooves in their longitudinal directions.

The flange 28 is shown cut away at two places 34. near the cam 16 and at opposite sides of its vertical plane of symmetry, and through-the said openings the loops of the yarn are drawn in and out. when the nee-' dles are placed in the manner hercinbe'fore described in their outer noperative positions they must be prevented from dropping through the openings 34. To this end an are 35., suitably of angleiron, is placed outside the openings 3 said are having an up wardly projecting flange 36 extending at a distance from the edge of the disk 2 corresponding to the lengths of those parts of the needles which are outsidcthe disk 2- when the needles are in the outer inoperative pothe raised parts 14; of the disk 2 serving as stops for the arm 12. Placed at the ends of the are are jaws 37 adapted to catch the outer .ends of the outwardly moved needles 5 and cause the same to enter upon the arc. The outer ends of the needles then bear on the flange 36 of the arc and the needles are thus Prevented from dropping.

In the modified form of the disk 2 shown in Fig. 5 the disk is not open at its lower side so as to allow the needles to freely move inward and outward but instead thereof the disk has a num r of grooves through which the needles may be moved from operative into inoperative positions or vice versaf In the embodiment shown the disk 2 has a workinggroove 3S,- and at both sides of the 3 same are grooves 39 and 40 concentric with the former. Placed between the grooves 0 38 and 39 is a guiding tongue 41', and placed in the groove 40 is a further guiding. tongue 50. lVhen the needles are working, the guiding tongue 41 is placed across the outer groove'3fi. If they are to be moved outward into inoperative positions, the guiding tongue 41 is placed across the groove 38 so as to cause the needles to move outward intothe groo e 39. If the needles are tobemoved inward rom the groove 38 into inoperative positions, this may be effectedby hand after placing the disk 2 in a position in which the needles to be brought out of operation are just opposite one of the obliquely extending grooves {12 connecting ac he grooves 38 and 40. I

As long as the needle heads a to be retained inthe groove 40 the guiding tongue 50 takes up the position shown by full lines. If, on the contrary, the guiding tongue is .3 swung outward into the position shown by dashed and dotted lines, the needle butts are caught and moved outward through the transverse groove 42 into the working groove 38. 5 Fig. 6 shows merely schematically a modified form ofthe frame in which the operating man. 43 is placed at the foot of the standard and connected through gearing 49 to a hollow shaft extending 50 through the standard and carrying the disk 2. The .yarn from the reel 8 passes through the hollow shaft and thence in the manner horeinhefore describedto the yarn-guide 13. The part carrying the reel 8 is shown connected to the shaft 45 so as to rotate with the same. by which twisting of the yarn is prevented.
